Device for efficient demagnetization of long-length articles

This paper describes a method for demagnetizing long-length ferromagnetic articles. The demagnetization method is based on the use of the constant magnetic field corrected according to the measured initial and residual article magnetizations in the demagnetizing process. The advantage of this method is the capability of the qualitative demagnetization of extensive ferromagnetic articles of large sections with high velocity and small power input.
